Percutaneous Transluminal Renal Artery Angioplasty Using the Coaxial Technique

Abstract

PTRA with a guiding catheter can be performed in most patients with a high success rate and a low complication rate. This study points to two major problems with PTRA: the high restenosis rate and the low response to treatment of hypertension. The careful selection of patients for PTRA is important for increasing the success rate, and follow-up to detect restenosis is mandatory.
